Hey guys, I just thought that it would be nice for us to compile a list of warm up puzzles/problems. The purpose of warm up problems is to get you in the mind set for attacking more sophisticated problems/puzzles (ie, focus). These puzzles should be mathematical in nature. They should also be reletivly easy, but not too easy that you don't have to do anythinking.

Anyways, here are 3:

1. Without using a calculator, determine the number of zeros at the end of 25!
2. What fits better, a square in a circle or a circle in a square?
3. What fits better, a cube in a sphere or a sphere in a cube?

Of course, you can go about generalizing these problems.
